Enercon E-70 Installation in Russia

Sarens sets up WTG and other components of three E-70s,
with a capacity of 2.3 MW each, in Russia

Vetrotechnika commissioned Sarens to install three new turbines,
the Enercon E-70s, having a height of 65m each, near the village of
Ushakovo - 20km south of Kaliningrad in Russian. Working below
-18°C with wind speeds above 10m/s during installation, Sarens five
member crew safely completed the project.

The modular towers, each 65m high, were topped with the nacelle
and generator, weighing a combined 71T. Our team deployed Liebherr
LTM 1750-9.1 TYVEN/27.2m(49.1m) + 9m + 28m/CW114T. This crane is
capable of working with two hooks for hub with blades installation.
LTM 1750-9.1 reached the job site by 12 trucks from Gdansk, Poland
in three days and was assembled in around seventeen
hours.

The installation of the turbine was carried out in defined
stages. First, a base ring with a weight of 18T followed by
electric modules were installed. The following modules, 3 sections
with a weight of 54T (height of 17.5m), 38T (height of 35m), and
42T (height of 65m) were raised and mounted. Once all the sections
were installed, a Nacelle weighing 19T (radius - 28.5m) and a
generator weighing 52T (radius 26.5m) were mounted at a height of
65m. Finally, the hub with blades was assembled. The length of one
blade was 35m. At the final stage, using two hooks, a rotor
assembly with 51T blades was raised and
mounted.

Project Manager, Suprunets Dmitry says, "Despite severe weather
conditions Sarens' team successfully completed the WTG building
project in accordance with the client's cost and timelines." The
client, Yuriy Kravchenko adds: "I want to say thank you Sarens'
team for their professionalism. Work has completed fast and with
high quality".
